Abstract
A multi-view display is switchable between single view and multi-view modes, and uses lenticular means () arranged over the display panel which comprise birefringent electro-optic material () adjacent a non-switchable optically transparent layer (). The non-switchable optically transparent layer () has a refractive index (n) substantially equal to the extra ordinary refractive index of the birefringent electro-optic material (). In the single view mode, the birefringent electro-optic material () defines a non-switched state, and the polarization () of the light output from the display panel and incident on the lenticular means is linear and aligned with the optical axis of the birefringent electro-optic material () at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material () defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.
